MACHINE FOR MAKING SOLES.

Specification of Letters Patent.

Patented Dec. 5, 1916.

To all whom it may concern:

Be it known that I, EDWARD E. ORR, a citizen of the United States, residing at VVeymouth, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Machines for Making Soles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to machines for making soles and more particularly to edge beveling or chamfering mechanisms adapted for use in sole fitting machines.

The invention is an improvement on the edge chamfering mechanism described in United States Letters Patent to William Gordon No. 989,142, granted April 11, 1911, and for purpose of illustration is shown as applied to the Economy channeling machine disclosed in United States Letters Patent to William C. Meyer No. 984,773, granted February 21, 1911.

The objects and advantages of an edge chamfering mechanism in the manufacture of insoles is fully set forth in said patent to lVilliam Gordon, but those skilled in the art will recognize that the utility of the invention is not confined to a combination with the tools of a particular type of insole channeling machine or, in fact, to an application to any insole fitting machine for the edge chamfering may readily be performed as a separate operation. if thought desirable. It has been found desirable, commercially, to completely fit an insole in one operation and the edge gage of an insole channeler forms a convenient part to support a chamfer knife for beveling the edge of the unlipped surface of the insole.

The invention, as illustrated, is applied to a machine for channeling Economy insoles, but obviously it may be used with equal effect in making Goodyear welt insoles, or in providing a beveled edge on a sole of any type where such an edge is deemed desirable.

The various novel features of the improved edge chamfering mechanism will be apparent to those skilled in the art from the following description of its preferred construction and the accompanying drawings illustrating that construction, in which,

Figure 1 is a front elevation of the work support and adjacent tools of the machine of said patent to lVilliam C. Meyer with the improved chamfer knife mechanism mounted on the edge gage, Fig. 2 is a plan of the work support and chamfer knife mechanism illustrated in Fig. 1, Fig. 3 is a front elevation of the chamfer knife mechanism, showing also a portion of a sole, in cross-section, being operated upon, Fig. 4 is a horizontal section on the line 44 of Fig. 3, Fig. 5 is an enlarged vertical section on the line 5-5 of Fig. 3, Fig. 6 is a fragmentary detail, in elevation, of the operative end of the edge gage, and Fig. 7 is a fragmentary detail, in elevation, of the rear side of the operative end of the edge gage.

In the embodiment of the invention illustrated in the drawings the portions of the Economy channeling machine which are illustrated are the channeling knife 1 and its block 3; the edge slitting knife 11; both knives being mounted on the knife carrier 9; the work support 35, its stem 36, slide 37 and its operating toggle the four motion feed foot 45 and its carrier; and the edge gage 91 and its operating mechanism, all being designated by reference characters corresponding to those in said patent to William C. Meyer.

The edge gage 91 is provided with a dovetailed shank 46 (Fig. 5), which fits in a correspondingly shaped way in the edge gage supporting bracket 95, and the chamfer knife mechanism of the present invention is mounted upon the edge gage shank 46.

A chamfer knife block 47 is secured to the shank 46 by a pair of headed set screws 48 which pass through slots 49 on the block thus permitting adjustment of the block, and the chamfer knife 50 carried thereby, longitudinally of the edge gage 91 or across the line of feed of the sole being operated on. The block 47 is provided with a slot extending at an angle to the sole supporting surface of the work support 35 (preferably an angle of substantially 30) and the chamfer knife 50 is held adjustably therein by a clamping plate 51. By loosening the set screw 52 the knife 50 may readily be adjusted for wear. The sole engaging or operative, end of the edge gage 91 is provided at its rear side with an angular slot 53 (Fig. 7) in alinement with the knife slot in the block 47, through which the knife 50 eX- tends. The slot 53 does not remove any of the bearing surface at the end of the edge gage vide a stiff edge 3) secured by a set ported for as may be seen from Fig. 4. The setting of the knife in its block is such that its cutting edge 54 (Fig. 6) projects beyond the end of the edge gage and is thus in position to re move a small, beveled skiving from the unlipped surface, of any sole fed through the channeling machine having its edge pressed against the edge gage.

The margin of the sole in advance of the chamfer knife should be properly supthe certain action of the knife thereon and for this purpose the edge gage is provided with a forwardly projecting, sole support similar to the part having a like function in the mechanism of said William Gordon patent, except that as the present support must rest on the sole engaging surface-of the Work support 35 it has been made as a thin, tapered foot so as not to materially displace the sole vertically and also not interfere with the operation of the presser foot of the channeling machine.

Some tro'uble has been experienced in having a delicate foot of this character break, necessitating, when the foot is integral with the edge gage, replacement by an entirely new edge gage. Although not essential, it has been found to be advantageous commercially to make the sole supporting foot separate from the edge gage. The sole rest is preferably made as the thin, tapered, for- Ward portion 55 (Fig. of a plate 56 which is adjustably clamped to the bottom side of the edge gage. This foot extends forwardly to a position beside the cutting edge 54: of the knife 50. The rear side of the edge gage has a depending part 57 (Fig. 7 which is provided with an inner undercut rabbet (see Fig. 5,) and the plate'56, the rear portion of which is dovetailed in cross section, is clamped therein by a removable clamping block 58 also provided with an undercut plate-holding rabbet, held in place by a set screw 60. The block 58 is provided with a pair of steady or guide pins (see dotted lines Fig. 4:) which seat themselves in holes in theedge gage when the screw 60 is tightened.

Many insoles, more particularly splits, are soft and flimsy. Such soles do not proto guide by and as a result the work will chatter and produce an uneven cut. To overcome this there has been provided a device to hold the margin of the sole down upon the work support 35, in effect stiffening its edge and providing for an even cut in all kinds of sole stock. Such device comprises a screw 62 to the forward side of the chamfer knife block 47 and shaped at its forward end to curve about and embrace the operative end of the edge gage 91 above the foot 55 (see Fig. 4). The height of the spring presser 61 above the surface of the work support 35 is deterspring finger 61 (Fig;

mined by rotating a small washer or thumb disk 62 mounted above the presser, eccentrically on the shank of a headed screw 63 threaded into the block 47. Vith this construction the margin of the sole is held neling knife 1 acts to form the channel and channel flap, the edge splitting knife 11 acts to form the lip, and the chamfering knife 50 acts to form the bevel at the edge of the unlipped surface of the sole, the skiving removed passing beneath the chamfering knife through the opening between the edge of the knife and the sole supporting foot 55.

The nature-and scope of the present invention having been indicated and the preferred embodiment of the invention having been specifically described, what is claimed as new, is:

l. A machine for making combination, a sole support, an edge gage, a thin, tapered foot carried by said gage arranged to rest on the sole engaging surface of said support beneath the margin of the sole, and a chamfer knife cooperating with said foot arranged to act on the edge of the sole contacting with the support.

2. A machine for making soles, having, in combination, a sole support, an edge gage, means for operating on the margin of the sole, and a presser finger mounted on said gage having a portion extending beyond the operative end of said gage to engage the upper face of the sole and hold its margin in contact with the work support for the operation of said means thereon.

3. A machine for making soles, having, in combination, a sole support, an edge gage, means for operating on the margin of the sole, a presser finger mounted on said gage having a portion extending beyond the operative end of said gage to engage the upper face of the sole and hold its margin in contact with the work support for the operation of said means thereon, and means to vary the height of said finger above the work support.
